Subject: Re: [PATCH] media: platform: Fix missing error code in
 rzg2l_cru_start_streaming_vq()

Hi Jiapeng Chong,

Please repost with a proper subject line prefix: "media: rzg2l-cru:".

The 'media: platform:' prefix suggests a media/platform-wide patch, not a patch
for a single driver.

Why is this so hard to do?

Regards,

	Hans
